问题
—Could you have been more careful? —Why, what wrong______?
选项
A、did: do
B、will: do
C、have: done
D、had: done
答案
A
解析
语法题。根据前面的问句可知,这是在埋怨对方过去不够仔细,故选A。注意此题不可选D,因过去完成时只能用来表示“过去的过去”运作。请比较以下句子:We began to study English three years ago.我们是三年前开始学英语的。The experiment was done last week.那个实验上周就做过了。The problem had been discussed three weeks before.那个问题是在那时的三周前讨论的。When I came in he had just finished his work.我进来时他刚刚做完工作。Controlled rectifier circuits had been in use long before thyristors were invented.可控整流电路在可控硅发明之前早就采用了。Hardly had I reached the bus stop when the bus started.The teacher had no sooner finished his class than the bell rang.
